To investigate the litter amount and water-holding capacity under de-farming bamboo forests, Dendrocalamus(D) farinosus, Bambusa(B) pervariabilis ×Dendrocalamopsis(D) daii 3 and Bambusa(B) rigida, taking from Changning County of Sichuan Province, were determined in this paper. It could be concluded that thickness variation was from 33 mm to 51 mm and the litter amount changed from 6.88 t/hm2 to 9.46 t/hm2 under three different types of bamboo plantations. Litter amount of D farinosus was the most and that of B. pervariabilis ×D. daii was the least. Results also showed that dynamic changes of water-holding capacity, water absorption rate and immersion time of different litter was similar. The rapid changes were observed within 0~2 h, and then it slowly changed in the following six hours. The change stabilized after 8 h. Water-holding capacity, interception rate and the effective interception rate of D. farinosus were the best and the values were 36.52, 32.53, 27.05 t/hm2, respectively. The next was B. rigida(30.33, 28.33,23.83 t/hm2) and the last was B. pervariabilis×D. daii(28.35, 25.89,21.63 t/hm2).
